LIQUID-SOAP-DISPENSING DEVICE.

Patented datum 191W.

Application filed April 15. 1914. Serial No. 831,898.

To all whom it may concern:

Be it known that I, EARL GQWATROUS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Liquid-Soap-Dispenstion' upon the horizontal top plate of a lava tory, with the liquid-soap receptacle or container located beneath s'uch plate, and pref' erably hidden from view, and'the delivery spout and operating device of the soap ejecting means located above such plate, in convenient position for use.

In the accompanying drawings I have illustrated a. preferred form or dispensing device of such' character, which I have designed for use in railway cars, and which 1s, now in extensive use n the lavatories of Pullman sleeping cars, where-the dispensing device is secured to the-sheet metal top or the lavatory, with thesoap-container beneat hsuch'top andhidden from view, and the dispensing device alopve it in convenient position for use at one side of the" lavatory bowl. In said drawings Figure 1 isa vertical s'ectionof such a dispensing device so applied and adapted. for use, with certain of its parts shown, in elevation; Fig. 2 a sectional detailfof the upper movable part f the dispensing device; .and Fig. 3 a horn llt) zontal sectional view through the fixed cap or the dispensing device which rests upon the lavatory top, on the dotted line, 3-3 of Fig. 1. The same letters of reference are used toreprescnt the corresponding parts in the several views. r

In the present instance A represents the horizontal sheet metal top of a'lavatoryt such as those commonly found in Pullman cars, which plate is provided with a circular opening concentric with the axisof the dispensing device to be applied to it. The soap-container of the dispenslng dev ce is shown as av pear-shaped receptacle-B, preferably of heavy. glass, havingan open up-v per end ofsomewhat greater diameter'than the circular opening in the plate A, and

provided at the center of its lower end with a smaller opening having a short projecting boss formed around it.

Resting upon the top of the plate A is a metal cap C, whose lower edge is of somewhat larger diameter than the circular opening in said plate. This cap C is provided upon its under face with a plurality of vertically depending integral arms a, having inturned lower ends formed integral with and supporting an internally threaded ring I) which is engaged by the externally threaded upper end of an axial tube D extending downward through the container B to the lower part of the latter, and there having threaded upon its lower end the upper end of a cylinder E, whose lower end in the present instance is prolonged into the form of a threaded bolt F which extends through the opening in the bottom of the container B and has screwed upon it a cap-nut G provided with a cup-shaped flange G COI'IttIIIIIIIg a packing ring (l' which seats against the external boss formed around'the opening in the bottom of the container B. A similar but larger packing ring H is interposed between the top of the container B and the under side of the lavatory plateA, and by tightening up the nut G the parts 'ofthe dispensing device may be firmly clamped to and supported by the plate A, with tight joints at both the top and bottom of the container.

The cap C is provided in the present instance with additional depending arms or lugs a, the outer edges of which, together with those of the lugs a, form a circle snugly fitting withinthe openings in the lavatory plate A and packin ring H, and serving to prevent lateral disp acement of the cap and ring. The cap is further provided upon its under side with a locking lug a integral with and projecting'outwardly from one of the lugs a and engaging a notch cut in the circular edge of the opening in the plate A,

for the'purpose of preventing the cap from being turned" upon saidplate.

Located within the cylinder E, m the lower part of the container B, is a piston I which is carried by a tubular piston-rod J which opens through the piston I into the interior'of the cylinder E beneath said piston. The rod J extends vertically upward through the tubular'casing D, and .at its upper end is secured to and carried by a vertically movable pressure-piece K and communicates with the discharge passage of a dc livery spout L formed integral with the part K. The latter is of generally cylindrical form, and its lower portion extends through and is guided in a circular opening in the top of the cap C concentric with the axis of the fixture, a vertical bead 6 formed upon one side of the cylindrical portion of the part K and engaging a notch in the edge of the circular opening in the cap C serving to prevent turning of the part K within the cap C. The vertical inner faces or edges of the arms (1 depending from the cap- C are coincident with the circular opening. in the latter and form a prolonged guideway for the part K.

Located within the cylinder E, beneath the'piston I, is a coiled spring M, which serves to yieldingly hold the piston in and return it to the upper end of the cylinder,

and consequently to hold the pressure-piece K and delivery spout L in their normal eletubular piston-rod J and out the delivery,

yated osition.

The cylinder E is in the present instance provided in its bottom with an inlet port N controlled by a check-valve O in the form of a ball resting in a recess-in the bottom of the cylinder, through which the contents of the container B are permitted to enter or be drawn into the cylinder E, but through which they are prevented from escaping by the check-valve 0.

Under the above described construction,

whenever the pressure-piece K at the top of the dispensing devlce is depressed and the piston I forced downward in the cylinder E, the contentsof the latter, beneath the piston,,will be forced upward through the spout L, and when pressure upon the pressure-piece K is relieved the spring M will restore the partsto normal position and lift the. piston I, and thereby draw a fresh supply of the contents of the container B into the cylinder E through the port in the bottomof the latter. Instead of the port N in the bottom of the cylinder, controlled by a check-valve, the cylinder may be provided with an inlet, port in its side, immediately below the'normal elevated position of the piston, through which the contents of the container may flow into the cylinder, and beneath which they will be trapped by the iston when the latter is depressed and be forced up through the tubular piston-rod,"

but the construction shown, in which they are sucked '.or drawn into the cylinder,

through the port in itslower end, when the piston rises, is preferable.

.The upper end of the tubular 0r cylindrical pressure-piece K is closed by a screw cap .P, by removing which the container may be refilled at its top, through the part K, when its contents are exhausted, without disturbing the fixture in any way.

drawing consists in the manner of secur- .ing the upper end of said rod in the pres sure-piece K and placing it in communication with the delivery nozzle L. This is accomplished in the present instance by extending the upper end of the tubular rod J laterally, in the form indicated by the dotted lines, and casting it directly in the delivery spout L when the latter and the pressure-piece K are formed. This serves not only to firmly secure the upper end of the rod J in the pressure-piece K, but provides a continuous, unobstructed and smooth delivery passage-for the contents of the container all the way from the interior of the cylinder E to the tip of the delivery, nozzle L, and at the same time leaves a free passage around the upper end of the rod J, within the pressure-piece K, for the refilling of the container, when the cap P is removed, as heretofore explained.

As will be-understdod from the foregoing explanation; I have provided a simple and efficient liquid-soap dispensing device, adapted to be readily and securely aflixed to a lavatory top, with the container located beneath said top and hidden from view, and the delivery spout and dispensing device located above the lavatory top, in convenient position for use at the side of the lavatory bowl, and have provided means for readily refilling the container at any time without in any way disturbing the position of the fixture or its attachmentto the lavatory.

While I have illustrated and described my invention in the best and most advantageous form known to me, and one in which it has gone into extensive and satisfactory use, it will be manifest that some of its features may be embodied and their advantages attained in other forms as well. For instance, while the particular means shown and described for securing the dispensing device to a lavatory top, with the receptacle or container beneath said top and the pressurcpiece of the dispensing device extending above the top into convenient position for use, such means consisting of the cap resting upon the top and the screw connection between said cap and the container beneath the top, by means of whichthe latter is clamped between the cap and container, is a very desirable and advantageous feature of my novel dispensing device in its preferred v form, it is evident that the container might me ian be secured to the under side of the lavatory top by other means and many of the advantages of my invention in other respects retained, the cap above the top of the lavatory in such case either being omitted or employed merely as a closure and finishing member, secured in any suitable way upon the upper surface of the lavatory top.

O ther variations of and departures from the specific construction embodied in the preferred form of my invention illustrated in the drawing will readily occur to those familiar with or considering such fixtures, and I therefore desire it understood that my invention, in its broader scope, is not in tended to be limited to the particular construction and arrangement of parts shown.
